“…This problem does not appear in the SD+E3 method, since everything there is expressed in terms of Coulomb integrals which can be modified according to Eq. (6). While such modification is as straightforward as for perturbation theory codes, technically it is not an easy task.…”

“…One must account for the change in electronic structure caused by the change in nuclear charge radius. The change in neutron distribution presents a separate problem [6] that will not be discussed further in this work, since the isotope shift is not sensitive to the changes in the neutron distribution. The change in the nuclear charge radius can be obtained by comparing experimental and theoretical values of isotope shifts.…”

Calculation of isotope shifts for cesium and francium

We perform ab initio calculations of isotope shifts for isotopes of cesium (from A=123 to A=137) and francium (from A=207 to A=228). These calculations start from the relativistic Hartree-Fock method and make use of several techniques to include correlations. The field (volume) isotope shift is calculated by means of an all-order correlation potential method and within the singlesdoubles partial triples linearized coupled-cluster approach. Many-body perturbation theory in two different formulations is used to calculate the specific mass shift. We discuss the strong points and shortcomings of the different approaches and implications for parity nonconservation in atoms. Changes in nuclear charge radii are found by comparing the present calculations with experiment.

“…The study of the PNC for a chain of isotopes does not require atomic calculations and can deliver useful information about either neutron distribution or new physics beyond standard model (see, e.g. [10][11][12]). The measurements of anapole moment does require atomic calculations but high accuracy is not critical here.…”

We use correlation potential and many-body perturbation theory techniques to calculate spinindependent and nuclear spin-dependent parts of the parity nonconserving amplitudes of the transitions between the 6s 1/2 ground state and the 5d 3/2 excited state of Ba + and Yb + and between the 7s 1/2 ground state and the 6d 3/2 excited state of Ra + . The results are presented in a form convenient for extracting of the constants of nuclear-spin-dependent interaction (such as, e.g., anapole moment) from the measurements.

“…On the other hand, sufficiently accurate atomic PNC experiments would provide a unique method to measure neutron distributions in heavy nuclei. Two major issues affect the interpretation of atomic experiments and will become more crucial as experimental accuracy improves, namely the small but not negligible effects of nuclear size and structure, [1] and the reliability of the atomic theory of heavy atoms [2,3].…”

Atomic parity nonconservation: Electroweak parameters and nuclear structure

There have been suggestions to measure atomic parity nonconservation (PNC) along an isotopic chain, by taking ratios of observables in order to cancel complicated atomic structure effects. Precise atomic PNC measurements could make a significant contribution to tests of the Standard Model at the level of one loop radiative corrections. However, the results also depend upon certain features of nuclear structure, such as the spatial distribution of neutrons in the nucleus. To examine the sensitivity to nuclear structure, we consider the case of Pb isotopes using various recent relativistic and non-relativistic nuclear model calculations. Contributions from nucleon internal weak structure are included, but found to be fairly negligible. The spread among present models in predicted sizes of nuclear structure effects may preclude using Pb isotope ratios to test the Standard Model at better than a one percent level, unless there are adequate independent tests of the nuclear models by various alternative strong and electroweak nuclear probes. On the other hand, sufficiently accurate atomic PNC experiments would provide a unique method to measure neutron distributions in heavy nuclei.1 12.15.Ji,12.15.Mm,31.10+z Typeset Using REVTEX
